A method for conveying auditable information regarding provenance of a product that is cryptographically accurate while retaining complete anonymity of product and participant on a blockchain includes: receiving a product identifier; generating a digital token by applying a hashing algorithm to the product identifier; generating an entry value by applying the hashing algorithm to a combination of an event identifier and the digital token; generating a digital signature by digitally signing a data package using a private key of a cryptographic key pair, where the data package includes at least a blockchain address, the event identifier, and the digital token; and transmitting the blockchain address, the digital signature, and the entry value to a node in a blockchain network.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 2, wherein the event identifier indicates sending of a product associated with the product identifier and the secondary public key is associated with a recipient entity of the product.
12. The system of claim 11, wherein the event identifier indicates sending of a product associated with the product identifier and the secondary public key is associated with a recipient entity of the product.
14. The system of claim 10, wherein the one of the plurality of nodes in the blockchain network validates the digital signature using a public key of the cryptographic key pair.
